    摘要: There is provided a method of manufacturing a molded article formed with a thermosetting resin and an injection molding apparatus so that occurrence of blurs and containing of bubbles at the time of molding can be prevented. Provided is a method of manufacturing a molded article formed with a thermosetting resin by using a mold including: a cavity for molding a product part; a gate which commutes with the cavity to guide a liquid thermosetting resin into the cavity, thereby forming a gate part; a runner which commutes with the gate part to guide the liquid resin into the gate part, thereby forming a runner part; and an overflow catcher which commutes with the cavity to receive the liquid resin overflown from the cavity, thereby forming an overflow part, wherein the method includes: an injecting process of injecting the liquid resin from the runner through the gate to the cavity, until the overflow catcher is filled from the cavity; a hardening process of heating the liquid resin in the mold, thereby hardening the liquid resin; a demolding process of demolding a resin molded article having the runner part, the gate part, the product part, and the overflow part from the mold; and a cutting process of detaching the gate part and the overflow part from the product part of the demolded resin molded article.
